Human Factors for CPRS Melissa Eggink Jennifer Wagner August 2012
What is “human factors”? Poll Question Ergonomics- door knobs and chairs Common sense Usability Optimization of processes and systems for the humans that work inside of them
Objectives • Understand how Human Factors principles improve usability and reduce the probability of human error • View examples of tools "before" and "after" the application of HFE concepts • Use multi-media to demonstrate concepts like "Usability" • Use that knowledge to discuss ways to make CPRS tools more intuitive for users
Admission Orders Medical Observation
What time will the medication be administered to your patient? A) 9:00 AM B) 5:00 PM C) Now D) Both A) and B) E) It won’t/ never
Outline • Demonstration • Usability principles with examples • Q&A time
PRINCIPLE Show users where they are in the system
PRINCIPLE Be consistent
Is the shape of the door handle consistent with the wording?
PRINCIPLE Consider users’ mental models
Is: 3 2 1 G consistent with users’ mental models?
What changed? Poll Question Coffee mug The side on which the woman held the phone Color of kitchen tile Picture on the wall The type of chair in which the man was sitting Some combination of the above
PRINCIPLE Be aware of conventions or standards
PRINCIPLE Provide meaningful feedback
What should the nurse do differently to avoid receiving this error message in the future?
PRINCIPLE Provide info when and as it is needed
PRINCIPLE Use simple/ natural dialogue
PRINCIPLE Minimize need to rely on memory
PRINCIPLE Use the system to stop errors before they happen
PRINCIPLE Give users an obvious way out
PRINCIPLE Make important functions obvious
PRINCIPLE Create a clear visual hierarchy
Would the average user know they cannot type in this boilerplate?
Where can I go for more? • See handout for references • Within VHA: • MidWest Mountain Veterans Engineering Resource Center Request assistance: http://go.usa.gov/RVv • VA IDEA • OIA Human Factors • OIA training • hi2 curriculum • Search ‘usability’ in TMS
Test steps: • Identify critical goals of product/tool/application • Define typical user • Conduct critical tasks • Identify task issues/general usability issues • Compile analysis/make changes to improve
